A chiral polyhalogenated 4,4′-bipyridine derivative is described allowing an easy access to a new family of chiral 4,4′-bipyridines by site-selective cross-coupling reactions. The absolute configurations of all the HPLC separated enantiomers were determined by X-ray diffraction and electronic circular dichroism coupled with time-dependent density functional theory calculations.
描述了手性多卤代的4,4'-联吡啶衍生物,其允许通过位点选择性交叉偶联反应容易地获得新的手性4,4'-联吡啶家族。通过X射线衍射和电子圆二色性以及与时间相关的密度泛函理论计算,确定了所有HPLC分离的对映异构体的绝对构型。
